Connor makes one-fourth of his shots in the goal. Could a 12, equal section spinner be used to develop a simulation for this situation? If yes, explain how. If no, explain what could be used instead.
Yes, because 1/4 is equal to 3 out of 12, so the 12 sections can be broken into 4 equal parts to show 1/4.
